Italy's transport minister says Britain should take in 141 migrants picked up by a rescue ship that sails under the flag of the British territory of Gibraltar.

Italy continues to refuse port to ships run by humanitarian groups, and Danilo Toninelli said Monday on Twitter that Britain should take responsibility for the migrants aboard the Aquarius, operated by French humanitarian groups.

Toninelli said the rescue was coordinated by the Libyan coast guard and that the ship was now in Maltese waters.

The French aid groups SOS Mediterranee and Doctors Without Borders have called on European nations to identify a close port of safety so the 141 migrants picked up in two rescues Friday could disembark. Most of the migrants are from Somalia and Eritrea and include 67 unaccompanied minors.
